| 504440 | 2006-12-05 09:10:00 | got this AC to DC adaptor but it died got another one that's the same but just a different plug at the end so i thought i might cut the plug off this broken one and attach it to the working one but i'm not sure to cut because this adaptor got this round cylinder thing before the plug not really sure how to describe it so took a photo pic (www.zshare.net) so.. should i cut at location 1 or 2..ie before or after that cylinder thing?? |

| 504441 | 2006-12-05 09:52:00 | The "round cylinder thing " is a ferrite sleeve for interference suppression. That is good but normally not essential to have, so if you can include it in your new set-up, good. If not, don't worry too much. (It is not connected to any conductors, just fits outside the insulation.) | R2x1 (4628) | ||
| 504442 | 2006-12-05 09:56:00 | um..hah..my comp clock shows 10:47pm but R2x1 replied at 10:52pm..anywayz..funny forum clock.. so it's called ferrite sleeve..um.. funny how most adaptors i have don't have it thanks or the reply~ now i can continue my little project :D |

| 504443 | 2006-12-05 10:43:00 | The ferrite sleeve is to suppress interference which may be generated (by the widget powered by the adaptor) from being radiated by the supply lead. It just sort of "swallows" the high frequency noise and turns it to heat. Some equipment is fairly "noisy" electrically speaking. If the FCC or other regulating body requires it to be cured, a ferrite sleeve just clips over the lead and reduces the interference to other equipment. And the forum clock? It has seen the light so often, it has a bit more daylight saving than the rest of us. | R2x1 (4628) | ||
| 504444 | 2006-12-05 16:32:00 | ..........the forum clock? It has seen the light so often, it has a bit more daylight saving than the rest of us......... Ya gotta remember that NZ is currently having their days getting longer...at least until Dec 22nd, and then they'll slowly get that clock back to normal again...:D . BTW: ferrite torroids are bi-directional, and they can keep attenuated freqs out, as well as in ....they don't care what the source of the noise is...and they come in various sizes and attenuation values.....someday I'll tell about them and 72mhz radio controlled aircraft. |

| 504445 | 2006-12-05 21:04:00 | got this AC to DC adaptor but it died. Got another one that's the same but just a different plug at the endCut after the ferrite, and make sure that the voltage and polarity are the same. i.e. they should both have the same voltage output and the + and - signs should be the same for the inner and outer connections. You also need to check that both are DC. If one has ~ next to the plug symbol, that is AC and will almost certainly stuff any DC appliance you connect it to. There is more to this than just "looking the same". You also need to "stagger" the inner and outer connections to avoid short circuits when you join them i.e the joint for the + wires should lie alongside unbroken insulation for the - wires and vice versa, then tape over the lot. It makes for a longer joint but a safer outcome. Cheers Billy 8-{) |

| 504446 | 2006-12-05 23:13:00 | i've checked everything..voltage, max current, polarity, both dc..so all good i've finished what i was doing now seems to work fine..i kept the ferrit though..ohwell |
